#29801 Re: Human missions » Congress Cuts NASA's Budget On Apollo Anniversary - A no no for Bush's budget increase » 2004-09-23 09:01:30

This article fills in the gap on the why an amendment was put forth with the extra money for shuttle and hubble.
It appears that the senators are looking at when the 2010 to 2014 timeline for a usefule CEV would be available as a concern.

Yesterdays florida today article had a one liner on robotic moon missions.

quote:
That figure does not include $29 billion for robotic missions to scout the moon.

So if we are going to the moon we will have to rely either on old data of from other nations and just wing it hoping for the best if the money does not get put back in at a later date.

Any system that we send will not only look for life in the atmosphere but below ground as well. This article points towards technology for the detection of virus on Earth but I think some forms of life will be very simular.

It appears that even though Nasa will get more money in the 2005 budget versus the 2004, there is still the need in order to make ends meet for the initiative leading Nasa to cut or delay science or even robit missions or programs.

#29806 Re: Human missions » Where exactly is Mars Direct with NASA? - Are they going to do it or not? » 2004-09-22 19:57:47

Well I have been thinking of the 3 ship senerio and of the time line for each noting that any one that fails puts the mission in jepody and that each ship even if they are somewhat modular are really 3 very different ships in design.

My though would be to spread each of the basic functions across all equally but that also precludes a very acurate landing system such that each could be within meters of each other not miles. If that is not possible then I feel that some means to make them somewhat mobile is in need to get them into closer proximity to each other.

Next thought was on crew size, when we did apollo there was a crew of 3 though 1 was left in orbit. If each is of a balanced design with each having 3 crew mebers then the total on the surface of 9 is very attractive to making the mars base with a high degree of chance for sucess.

#29807 Re: Human missions » The need for a Moon direct *2* - ...continue here. » 2004-09-22 19:45:12

I hope that the new CEV and lander combo is not designed like the old apollo for a 3 man crew one had to be left in orbit, not all that practical. Also any design should address the Mars landing formats to allow for the least amount of cost later.

It only took 12 days of radio silence but they are back and Nasa has found a way to fund them for continued research.
Both rovers have done a great job.

Could the next rovers have a side car, I want to take a short ride while they explore the surface just joking I am sort of tired of arm chair viewing.

Replacement by the barrel for atmosphere, should be real costly trucking it in from where ever it can be supplied from.

How does one slow the effect? Gravity seems to have some part in the equation, another is magnetic field and indirectly the mass of the planet I think is the last. But how can we effect changes to either on a planetary scale or of how much of a change is needed to stop or slow this from happening?

#29812 Re: Human missions » The Case Against Mars - Why Mars is not a good target! » 2004-09-22 10:11:06

Another reason why mars is a poor choice may be due impart to our current fuel tank technology and or fuels.

Misbehaving liquid sent into space
http://www.newscientist.com/news/news.jsp?id=ns99996435

A satellite filled with water will show how liquid sloshes in space, helping engineers design better fuel tanks for future spacecraft. Unpredicted waves in the fuel tanks of rockets and spacecraft have been blamed for several mishaps in the past. Now, as spacecraft components get smaller and missions grow longer and more ambitious, fuel tanks represent ever-larger proportions of the craft. "A little fluid motion in old spacecraft wouldn't have been a big problem but for new ones it's causing trouble.

The satellite was originally scheduled to fly aboard a NASA space shuttle. But after all the shuttles were grounded following the Columbia disaster in 2003, the project was shifted to the Ariane 5 ECA rocket, designed to carry payloads of 10 tonnes.

#29813 Re: Unmanned probes » JIMO - Jupiter Icy Moons Orbiter » 2004-09-22 10:02:03

The Jimo project has generated a certain amount of controversy due to its uranium-fuelled nuclear fission reactor. Which creates electricity to drive the "nuclear electric propulsion (NEP)" system. In simple terms, NEP uses the electricity produced by the reactor to ionise propellant atoms which can then be ejected at high velocity from the vehicle's propulsion system by magnetic or electrified grids.

NASA has already proven this "ion drive" technology aboard Deep Space 1, although electricity for the thrusters was in that case provided by solar panels.

Hey NASA! Send more MERs to Mars!

Send a few to some other places, like the Moon and Mercury.

They should be mass producing those things.

I agree, since making more than a few of something usually drives down the cost. Make only slight alterations to functional blocks of tools or of testing apperatus for what it is that we wish to learn from each mission.

#29815 Re: Space Policy » Space fairing Nations - The ever changing view » 2004-09-22 09:01:05

Well the verdict may be out on converting Nasa facilities into the federally funded research centers but it does appear that Nasa is following though with the commissions recommendations.

#29816 Re: Human missions » Congress Cuts NASA's Budget On Apollo Anniversary - A no no for Bush's budget increase » 2004-09-22 08:43:51

Results of yesterdays Appropriations  hearing.
As a result, there are some cuts, particularly in the exploration vision: $160 million cut from the CEV, $50 million from the robotic lunar exploration program, $10 million from Centennial Challenges, and an unspecified amount from Project Prometheus. These cuts, though, are less severe than what House appropriators approved in July.

NASA budget OK'd by Senate panel

Senate panel OKs extra money for NASA
Committee would reverse House budget cuts

http://www.msnbc.msn.com/id/6067433/


The Senate Appropriations Committee voted Tuesday to increase NASA's budget by about $200 million over the President's request, for a total of $16.4 billion.

http://appropriations.senate.gov/releas … ?id=226469

National Aeronautics and Space Administration (NASA): is funded at $16.379 billion, an increase of $200 million over the FY04 enacted level, and a reduction of $665 million from the budget request. An additional $800 million in emergency funding was added for NASA during the Committee’s consideration of the bill.

-- The return to flight activities for the Shuttle program are funded at $4.319 billion, the requested level from the Administration.

-- The International Space Station is funded at $1.6 billion. The bill reduces ISS operations by $120 million due to the continued reduced capability of the ISS for at least half of FY05.

-- The Moon/Mars vision:

--- The Crew Exploration Vehicle (CEV) is funded at $268 million.

--- A lunar exploration mission is funded at $20 million.

I definitely do not like how the budget funding wars are shaping up.

http://www.flatoday.com/news....OST.htm

Qoute:
Moon-Mars tab may hit $100 billion according to a new study from the Congressional Budget Office.

Dominating the cost: Plans to develop, test new rocket capable of lofting 100 tons to space, a new ship (CEV) for moon-bound astronauts capsule and a new lunar lander dominate cost.

Another alternative: living within its projected budget and pushing back the year during which U.S. astronauts return to the lunar surface. In that case, the study suggests, look for astronauts to land on the moon between 2023 or 2027.

Different options costly in money, relations, return-to-moon efforts
http://www.floridatoday.com/!NEWSROOM/l … BOSIDE.htm

NASA could save up to $43 billion by retiring the shuttle and bailing out of the International Space Station in 2005, a new Congressional Budget Office analysis shows.

Doing so might enable NASA to stage a return to the moon by 2016 instead of 2020.

#29822 Re: Human missions » Location » 2004-09-22 06:30:17

Polar location for base drives up energy comsumption in the form of needed heating is the only draw back as a singular base but add to that equation sending more of them, placing them on a line towards the equator, connecting one to another for sharing of resources like power, oxygen, water and more possibly include tunnels as part of the interconnection to each other.

Another thread also mention water and methane over lap in these areas in three broad equatorial regions: Arabia Terra, Elysium Planum and Arcadia-Memnonia, which might be just as favorable for bases to be placed at.

#29823 Re: Human missions » Where exactly is Mars Direct with NASA? - Are they going to do it or not? » 2004-09-22 06:07:31

I can say that I have never read the mars direct book and have only read what is in multiple versions of these or simular programs posted on the web. They all seem to place any stay on mars as more than the time to get there at a minimum, to the journey time plus one Earth year as a mid point and at the far end of the scale is the 2 year plus period. It does not matter to me how long so long as enough of the job of construction of a more permanent base can occur.

Also we are sending probes every 2 years to explore mars, due to orbital machanics so how could we send them every year and if so why is not Nasa on that time line instead for missions to Mars.

The section on the engines and fuels used is what gets my attention. The strap on and main for the lower stage launch being kerosene / LOX while the uppers boost to orbit is LH2 /Lox. This makes for a very economical rocket.
